Desalination

Sustainable desalination with maximum energy efficiency

According to the UN, water scarcity is one of the major challenges facing the world today and tomorrow. The need to find sustainable solutions for new freshwater supplies is urgent; solutions that take the straight road from saline to fresh water at low cost and with minimum impact on climate and nature.

Due to its high energy efficiency and reliability, Sea Water Reverse Osmosis (SWRO) is one of the most sustainable and cost effective solutions for converting sea water to potable fresh water. At the same time, SWRO technology undergoes rapid development to improve energy efficiency and support large-scale freshwater production.

Features and benefits

Extremely low energy consumption

Ultra-low maintenance costs

Simple to operate

Minimal service and long service intervals

Small footprint but effective, compact and light in weight

Danfoss takes lead in SWRO innovation

Danfoss is committed to supporting the desalination industry with energy efficient SWRO solutions. The product offering includes four core technologies, comprising high-pressure pumps, AC drives, energy recovery devices and pressure and fluid control devices. These combine into highly efficient and lasting water purification solutions that return energy savings of up to 65% compared to traditional centrifugal pump systems without energy recovery devices and drives.

Water from desalination

Today, 1% of the global water supplies come from desalination. The share of desalination is expected to grow significantly.

Increase in desalination plants

The past five years have seen a 57% increase in desalination plant capacity.

Savings on your plant

Optimized technologies combined with SWRO experience can increase energy efficiency by up to 65%

By land, by sea - anywhere

At large scale, reverse osmosis plants are capable of providing freshwater to entire cities while compact solutions are ideal for supplying hotels and resorts, ships, and offshore facilities with clean water.

The APP pumps are designed for SWRO in land-based and marine applications, offering the highest efficiency rates in the industry. The compact design, long service intervals and reliability of the APP makes it a first choice for small and medium-sized desalination plants.

DST P40I titanium pressure transmitter for harsh environments

For use in corrosive environments, Danfoss offers the new robust DST P40I pressure transmitter made of Titanium and with ceramic pressure sensing element. DST P40I is optimized for use in applications such as desalination systems, seawater cooling, and chemical processing.
